Need step-by-step guidance for migrating BIG-IP i2800 WAF to rSeries (UCS restore vs clean build)
Hello DevCentral Community, We are planning a hardware refresh migration from a legacy BIG-IP i2800 running WAF/ASM to a new rSeries platform and would like to follow F5 recommended best practices. Could you please advise on the step-by-step process for this migration, specifically around: o Whether UCS restore is recommended versus building config fresh o BIG-IP version compatibility considerations during the migration o Interface/VLAN mapping differences between iSeries and rSeries hardware o Best approach to migrate WAF/ASM policies and tuning after migration o Common issues or lessons learned during real-world cutovers Current environment: " BIG-IP model: i2800 " BIG-IP version: 17.1.3 " WAF module: ASM / Advanced WAF " Deployment: Active/Active Thank you .Bigip Restoration From Hardware to VM
Hi All, I wanted to know about the prerequisites and the proper steps to do the restoration test from an F5 r2600 Device to an F5 Bigip VM. So I have tried it and it comes with multiple errors 2026 Mar 17 18:10:15 Hostname.COM logger[3452]: Re-starting named Reloading License and configuration - this may take a few minutes... Broadcast message from systemd-journald@Hostname.COM (Tue 2026-03-17 18:10:21 IST): load_config_files[4013]: "/usr/bin/tmsh -n -g -a load sys config partitions all " - failed. -- 010713d0:3: Symmetric Unit Key decrypt failure - decrypt failure Unexpected Error: Loading configuration process failed. 2026 Mar 17 18:10:21 Hostname.COM load_config_files[4013]: "/usr/bin/tmsh -n -g -a load sys config partitions all " - failed. -- 010713d0:3: Symmetric Unit Key decrypt failure - decrypt failure Broadcast message from systemd-journald@Hostname.COM (Tue 2026-03-17 18:10:21 IST): load_config_files[4542]: "/usr/bin/tmsh -n -g -a load sys config partitions all base " - failed. -- 010713d0:3: Symmetric Unit Key decrypt failure - decrypt failure Unexpected Error: Loading configuration process failed. 2026 Mar 17 18:10:21 Hostname.COM load_config_files[4542]: "/usr/bin/tmsh -n -g -a load sys config partitions all base " - failed. -- 010713d0:3: Symmetric Unit Key decrypt failure - decrypt failure Configuration loading error: base-config-load-failed For additional details, please see messages in /var/log/ltm Is it all coming due to a mismatch of the Master Key or something? Both devices are in the same version, and I also verified the resource provisioning. I wanted to know the reason for this and also the proper steps to test restoration from F5 hardware to VM. SME's Kindly help me on this..
How to Perform Redundancy Switchover on BIG-IP
Regarding Redundancy Switching Methods on BIG-IP Can I understand that the following ① and ② exhibit identical behavior? If there is a difference in operation, please let me know. ① Force to Standby on the Active Unit ② Force to Offline ⇒ Release Offline on the Active UnitLB Connection Limit Detection Method
We have set a connection limit on the load balancer. If there is a way to detect when the upper limit of the connection limit is exceeded, please let us know. We are considering detection via log monitoring, but we would like to confirm if there are other methods available.
Configuration Assistance: Configure Email Alerts for HA Failover Events and Device Offline
We have a BIG-IP VE High Availability Pair deployed in Microsoft Azure. We need to configure the BIG-IP to automatically send an email notification to our Operations teams immediately when a Failover event occurs(When the unit goes from Active to Standby or Offline) Could you provide the recommended procedure for the configuration to trigger these email alerts?
